AUTOMATIC CHININEY-SWEEP.

ASpecification of Letters Patent.

Patented Oct. 14, 1913.

Application iled December 11, 1911. Serial No. 665,068.

To all whom, z't may concer-n.'

Be it known that I, LEROY R. Monats, a citizen of the United States, residing .at Longbeach, Los Jangeles county, California, have invented a new and useful Automatic Chimney-Sweep, of which the following is a specification.

My invention relates to the construction of an apparatus for cleaning iiues and chimncys.

The object of the invention is to provide a device which will utilize the shifting of air currents as a motive power and which will at all times automatically keep the chimney clean and free from obstructioii. The means by which these beneficial results are attained is set forth in the accompanying drawings, in which- Figure- 1 is a side elevation of my Chim ney cleaner and chimney in which it is used. Fig. 2 is a front elevation of the parts shown in Fig. l. Fig. 3 is a transverse section taken at a-a in Fig. 1. Fig. l is a side elevation of a series of chimneys, each containing a cleaner, and all operated in unison by a single wind vane. Figs. 5 and 6 are front and side views, respectively, of sections of sbafting utilized in my device and are intended to especially illustrate the construction of the couplings connecting the various pieces of shafting.

Throughout the several views like charactcis indicate like parts, and referring to the details of construction-6 is a. chimney upon which my device is used. 7 is a shafting supported vertically in the center of said chimney. This shafting is ordinarily made in one piece as shown in Fig. 1 and extends above the top of the said chimney. W'here conditions require, however, the shaft is made in sections and united with a suitable joint. One type of joint adaptable to this purpose is shown in Fig. and in Fig. 6. In this joint a fork S on one end of the shaft 7 engages recesses 9 in the adjacent end of the next piece of shafting. l0 is a wind vane attached to the upper end of said shafting 7.

11 is a supporting bearing on the top of the chimney.

12 indicates guide wheels attached to the shaft 7 at intervals to keep the shaft in the center of the chimney.

13 is a pin used to attach said wheel to said shaft. la refers to non-combustible bristles or metallic Scrapers attached to said shaft in one or more vertical rows. Each of these bristles is long enough to remain in contact with the Wall of the chimney during an cntire revolution of the shaft.

In F ig. 4 sprocket wheels 17 are attached to the shaft 7 and chains 1S pass over these and like sprockets 19 on other shafts 7 in adjacent chimneys. In this manner several shafts are made to revolve in unison and all may be operated by a single vane 10.

In use every change in the direction of the wind causes the vane to revolve a like amount. The vane being rigidly attached to the vertical shafting turns the shaft and the bristles move along Athe walls of the chimney, dislodging all particles of soot and keeping the chimney brushed clean at all times. A chimney equipped with this device will remain clean and thoroughly etilcient without further attention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is In a chimney cleaning apparatus: the combination of a chimney; a vertical shafting centrally suspended within said chimney; means for supporting said shafting; a wind vane rigidly attached to the top end of said shafting; guide wheels attached to said shaft at intervals within said chimney; and non-combustible bristles arranged longitudinally along said shafting adapted to come in contact with all portions of said flue while said shaft is being revolved one complete revolution.
